Major league baseball final standings
- January 19 – Eddie Mathews is elected to the Hall of Fame by the Baseball Writers' Association of America on 301 of 379 ballots.
- January 25 – The San Diego Padres send Dave Tomlin and cash to the Texas Rangers in return for Gaylord Perry, who will win this year's National League Cy Young Award.
- January 31 - Commissioner Bowie Kuhn voids the Oakland Athletics' trade of Vida Blue to the Cincinnati Reds, citing the "best interests of baseball" clause. As compensation, the A's send Doug Bair to the Reds for minor-league prospect Dave Revering.
- March 17 – At Al Lopez Field in Tampa, Florida, the Cincinnati Reds host the New York Yankees in a Spring training match-up wearing green uniforms in honor of St. Patrick's Day. In 1990, the Boston Red Sox become the second team to adopt this tradition.
- April 1 – Starting off with a bang, Japanese star Sadaharu Oh hits a grand slam home run on opening day. It is his 757th home run.
- April 13 – The New York Yankees defeat the Chicago White Sox 4–2 in their home opener on Reggie Candy Bar Day. Reggie Jackson slugs a 3-run home run in the first inning, and the field is showered with candy bars which were given out free to the fans at the game.
- April 16 – The St. Louis Cardinals' Bob Forsch hurls a no-hitter in beating the Philadelphia Phillies 5–0. Forsch walks 2 and strikes out 3 in pitching the first home no-hitter by a Cardinal since Jesse Haines in 1924. His brother, the Houston Astros' Ken Forsch, will toss a no-hitter the following season against the Atlanta Braves – making them the first big league brothers to each toss a no-hitter.
- April 20 – With two out in the top of the fourth inning, the Atlanta Braves' Jeff Burroughs hits a ground ball up the middle that San Diego Padres rookie shortstop Ozzie Smith dives for behind second base. As he was in the air, the ball hits the base and caroms behind Smith. As he is diving in the opposite direction, Smith reaches out with his bare hand and catches the ball. He bounces up, and throws Burroughs out at first. The Padres win the game 2–0.
- April 29 – Pete Rose smashes three home runs in a 14–7 win over the New York Mets.
- May 5 – Pete Rose singles off Montreal's Steve Rogers for career hit 3,000 and gets a hug at first base from former teammate Tony Pérez. The Montreal Expos beat the Cincinnati Reds 4–3.
- May 12 – At Royals Stadium, a potential game-ending routine fly ball becomes an Amos Otis walk-off inside-the-park home run as Reggie Jackson and Mickey Rivers collide in the outfield. The Kansas City Royals defeat the New York Yankees, 4–3. The misplay turns a sure Goose Gossage save into a sour loss for the current World Champion Yankees.
- May 14 – With the Chicago Cubs losing 7–5 to the Los Angeles Dodgers, Dave Kingman hits a two-run home run with two outs in the ninth inning to send the game into extra innings. Kingman, who had also homered in the sixth, hits his third home run of the day in the fifteenth inning to give the Cubs a 10–7 victory over the Dodgers at Dodger Stadium, and end his day with eight RBIs. Following the game, Paul Olden, a reporter for radio station KLAC in Los Angeles asks Dodgers manager Tommy Lasorda, "What's your opinion of Kingman's performance?" during his post-game interview. Lasorda goes off in a now-famous obscenity-laced tirade.

- May 20 – At Olympic Stadium, Willie Stargell of the Pittsburgh Pirates hits two home runs off Wayne Twitchell in a 6–0 victory over the Montreal Expos. His second is a 535-foot shot in the fourth inning that lands in the upper deck – the only fair ball ever to be hit there.
- May 23 – With the Oakland Athletics leading the American League Western Division (24–15), manager Bobby Winkles walks off the job. Jack McKeon takes over.

With Thurman Munson on first, manager Billy Martin wanted Jackson to sacrifice bunt. Jackson made a half-hearted attempt with the first pitch, and Martin removed the bunt sign.

It turned out that strikeout came in the ninth inning of a 3-2 loss to the Philadelphia Phillies.
- August 17 - This was the second of 6 straight seasons in which the New York Mets would finish either 5th or 6th place. In this game, the Mets lost to the San Diego Padres (with rookie Ozzie Smith on the team) 9-2 that would put the Mets in last place to stay for the entire season.
